And the Washington Post is now reporting two officials with the university's basketball program are among those feared dead.

The paper reports a sister of assistant coach Ginny Doyle says she was one of the three killed. The Post says Natalie Lewis, the director of basketball operations was also riding in the ill-fated balloon.

A spokeswoman for Lewis' family, Julie Snyder, told The Associated Press that Natalie Lewis' body has not been found. However, state police have described their search as an operation to recover remains. The remains of the pilot and the second passenger have been recovered after being found about 1,500 yards apart in densely wooded areas. They have not been identified.

More than 100 searchers were called in to scour the woods and fields of the central Virginia site of the crash for the third victim and any remnants of the balloon or its basket, state police said.

"The search continues for our beloved daughter and we remain hopeful and ask for your continued prayers," Lewis's parents, Patricia and Evan Lewis, said in a statement.

Snyder called Lewis "an amazing persona and a strong persona, an athlete engaged to be married."

Lewis was in her third year as director of basketball operations for the Richmond women's basketball program, according to a profile on the university's website. She was a four-year letter winner and two-time captain of the Spiders' swim team. The Buffalo, New York, native attended Nardin Academy high school.

Witnesses described a harrowing sight on the special preview night for the Mid-Atlantic Balloon Festival, which was set to open Saturday. The festival was canceled.

On the ground, "It was complete silence," eyewitness Nancy Johnson said. "There were people praying. It was horrible."

The balloon was among 13 that lifted off Friday night from Meadow Event Park, home to the State Fair of Virginia, and was approaching a landing site nearby. Two of the balloons landed safely before the third hit the live power line, according to police.

The pilot attempted to retain control of the balloon and snuff the fire and two passengers either jumped or fell from the gondola, state police spokeswoman Corinne Geller said.

"Then witnesses recall hearing an explosion and the fire continued to spread," Geller said.

She said another pilot who was interviewed by investigators described how the pilot tried to open vents to release extra-hot air in an attempt to keep the balloon from rising faster.

"Based on witness accounts, he did everything he could to try to save the passengers' lives," Geller said.

An air safety investigator with the National Transportation Safety Board said a preliminary report would be released on the crash in 10 days. Heidi Moats said investigators were seeking records on the balloon and the pilot.

Troy Bradley, past president of the Balloon Federation of America, said most serious accidents on balloons - including fires, electrocution or baskets becoming severed - happen after hitting power lines. Most of the time it's due to pilot error, he said.

Fatal accidents happen less often than with other types of aircraft, Bradley said.

"Hundreds of thousands of flights will go without any notice. That one that hits the news gets all the attention, but ballooning is a very, very safe form of aviation."

Johnson said the crash near the park about 25 miles north of Richmond occurred in an instant.

"One minute the balloons were hovering in a field behind Event Park, the next everyone is pointing at sky," she said.

Carrie Hager-Bradley said she saw the balloon in flames on her way home from the grocery and heard people yelling.

Donnell Ferguson said he was cutting grass when he saw a couple balloons passing by. One was low, barely at tree-top level.

"At first I saw a cloud of black smoke and then I noticed the basket on fire," he said. "Then it just took off real fast and disappeared."

Twenty balloonists from the Mid-Atlantic region were to participate in the weekend festival, said Greg Hicks, a spokesman for the venue. About 740 people attended the preview event.

"It's just a shocking situation for everyone," Hicks said.

Robert Rinck, who was operating a frozen yogurt concession, said he watched the balloons lift off against a beautiful sunset. A few minutes later, someone said a balloon was on fire. He looked up and saw fire coming from the balloon.

"I just didn't know why it was going up and not down," Rinck said.

Johnson, who went to the festival with her husband, photographed the balloon as it rose.

"I turned around and just automatically started taking pictures," she said. "It just kept going up, up, up in the air."

Some hot air balloons landed safely in Debra Ferguson's yard, The Free Lance-Star of Fredericksburg reported. One of the men in the balloons pointed up at another still in the air and said he thought it might be in trouble.

"As soon as we looked up, the thing blew up right there," Ferguson told the newspaper. "All I heard was, 'Oh my God, Oh my God,' and all you saw was the top of the balloon still flying, but all of the basket was gone. All of the flames just disappeared. ... It was like a match - poof - and then it was gone."
